ENVELOP-MACHINE.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed January 18, 1905. Serial No. 241,530.

To all whom it may concern:

Boit known-that I, LAFAYETTE MARCELL, a citizen of the United States, residing at Millbury, in the county of Worcester and State of Massachusetts, have invented a new and useful Envelop-Machine, of which the following is a specification.

A style of envelop which has lately come into extensive use is that shown and described in patent to Callahan dated June 10, 1902, No. 701,840. This consists of an envelop having an aperture in the body por-' tion thereof covered with transparent paper or tissue so that when the letter or inclosure is folded and placed in the envelop, the address will show through said transparency thus doing away withthe necessityof addressing the envelop. 1

In the manufacture of this particular style of envelop, the aperture in the body portion can easily be made when the blanks are cut, butconsiderable difficulty has been found in making an envelop machine or in providing an attachment to an envelop machine by which the transparent slip can be attached or seicured to the envelop as the same is made. These previous attempts, so far as I am informed, have worked on the principle of applying-a line of glue around said aperture and in forcing a pile orbunch of transparencies against the body portion of the envelop. This has the disadvantages that as one transparency is applied, the succeeding transparencies are apt To get covered with glue and spoiled: that more than one transparency is apt to be taken from the pile or bunch at each operation; and that the transparencies are apt to be glued to the cnvelops out of position, owing to the varying pressure obtained through the diminishing bunch or pile of transparencies.

The object of this invention is to provide an envelop machine or an, attachment to an envelop machine by which the transparencies can be rapidly applied and the obiections before noted, overcome.

I have shown, in this application for patent, my invention applied to an envelop machine of the wellknown Grant and Rheutan type.

In this type of envelop machine, the envelop blank is taken from the pile by a set of pickers which gum the blank and deposits it on a carriage. The carriage then moves backward carrying the gummed envelop blank a certain distance towards the folding box. The gummcd envelop blank is left in this position and the carriage returns for another blank. tion'of the carriage toward the folding box, the olan k which waslcit in the advanced position is pushed forward and one or more of such movements brings the blank into position to beforced by the folding plunger into the folding box. i "My attachment is designed to apply the transparency to the envelop blank while it dwells in its tint/cl toward the folding box, after it'is leit by, the first move- On the next 1110- mentor by the first and second movements of the carriage and bcforethe succeeding movement of the carriage moves the gummed blank into position'over the folding box. 7 h v My improved arrangement for applying-the transparency, as the blank dwells, consists of a plunger and a transparency holding box.. The plunger is fiat-faced and is provided with an air suction device. These parts are-so operated that the plunger descends into the box and then raises, lifting the uppermost transparency. Then the plunger descends and forcibly applies the transparency in proper position on the en'- velop blank, while it dwells as above indicated.

In the specific form of apparatus which I have shown, the transparency box has a movement under and away from the plunger and the plunger makes two reciprocations; one into the box and one to apply the transparency, for each cycle ofopilration in the machine. In this way the transparencies are picked up from the towel the pile, one at a time, before they are in any way gummed and the applying action of the plunger is the same for each envelop blank, whereby, when the parts are once carefully adjusted, the transparencies will be properly applied, in the same position and with the same pressure, one after the other to the succeeding envelop blanks. A

Referring, now, to the accompanying five sheets of drawings which form part of this application for patent, it will be seen that I have shown my invention applied to the envelop machine which is substantially represented, in patent to Rheutan No, 584,064, dated June 8, 1897. f I

In said drawings, Figure 1 is a side elevation of enough of said machine to show my invention attached thereto. Fig. 2 is a plan of the carriage showing the way the same operates. Fig. 3 is a'plan view illustrating my improved attachment. Fig. 4 is a rear elevation of the same. Figs. 5 and 6 are details of parts used for feeding the transparencies into the holding box. Fig. 7

is a detailed view of the cam mechanism which operates the applying plunger. Fig. 8 is'a detailed view of the operating mechanism of the holding box. Fig. 9 is'a perspective view of the operating means for putting the transparencies into the holding box. Figs. v1 0 to 15 inclusive, are diagrams illustrating the operation of. my attachment. Fig. 16 is a plan view of the gummed envelop blank; and, Fig. 17 is a view of one of the transparencies.

Referring to the drawings and in detail, designates the pickers or gumming heads which pick up'the envelop blanks, one at a time, and which deposit the same on the carriage F. This carriage is provided with a gripper or jaw F which seizes the middle point of the envelop blank. This jaw is mounted on a rod which has a spring tending normally to close the same, which rod is providcd with an arm at its end carrying a roll which strikes on cams, as the carriage reciprocateaso that the jaw will beclosed and opened to seize and release the envelop blank in a well-understood way. At the first movement of the carriage, the envelop blank will be left in the position indicated by dotted lines at the top of Fig. 2. At-thc next backward movement of the carriage, the envelop blank will be pushed by dogs 10 or other suitable devices to the position shown in dotted lines at the bottom of Fig. 2. At the next backward movement of the carriage, the envelop blank will be pushed by dogs ll- -ll, or'other devices, under the folding plunger G, which will drive the envelop blank down into the folding box. Thus the envelop blank, in this'movement llOll'l'iihC pickers to the folding box, has two dwells, a modification that has been made in practice of the machine shown and do- I scribed in said patent to Rhentan. While the envelop blank dwells in this second position; the transparency is applied and my invention relates to an improved means for performing this operation.

At the side ofthe machine is arranged a-receptacle 12 which has a door 13 and which receptacle is shaped to receive a large number of transparencies. Fitted to slide in ways in the envelop machine, parallel with the movement of the carriage, is a holding box 14 for the transparencies. When the holding box14 is in a rear position it registers with the receptacle 12.

Fitted into the bottom of the receptacle 12 is a bottom plate 15 which has a rod 16 extending down through the bottom of the receptacle. 12. This rod 16 is connected with an arm 17 which is bent-out from a rod 18 which is jeurnaled in bearings mounted on the ma- I chine. The rod 18 has a handle 19 at its end.

Fitted to slide in the receptacle l2 isa feeder block 20 which has projecting wings 21 and 22 arranged in different horizontal planes. The receptacle is cut away so that the wing 22 can project outside of same. Connected to the feeder block 20 is a link 220 which is connected to'an arm 23 mounted on a shaft 24 which carries a handle 25. g

When it is desired to place a number of transparencies in the holding box, the machine is stopped with the holding box 14 in line with the receptacle 12. The handle 19 is operated to raise the plate 15 up in the receptacle-to lift the pile of transparencies therein as far as possible. Then the handle 25 is operated to slide the feederblock 20 forward through the receptacle. This will push a pile of transparencies out of the receptacle into the holding box, said pile being determined by the distanoe between the wing 21, and the bottom of the feeder block. The wing 21 serves to hold the pile of transparencies thus shifted from bunching up and the wing 22 serves to hold down the transparencies remaining in the receptacle so that, as the feeder block is returned to normal position, the same .will not catch the uppermost transparency therein. In this way, transparencies can be put into the holding box in small bunches without handling.- The holding box is provided with a spring 40, as shown in Fig. 6 to hold the transparencies in proper place, after they have been shifted therein. The holding boxis reciprocated forward and backward by means of a cam 26 mounted on the camshaft, engaging which is a roller 27 mounted on a pivoted arm 28 which is pulled down by a spring. I The arm 28 connects by link 29 150 an arm 30 mounted I38-38 mounted on the cam shaft of the machine.

on a shaft 31 journaled in the machine. said shaft 31 are two arms 32-32 which connects by links 3333 to the holding box 14.

The holding box is made in the form of a solid box without a cover, as shown in section in Fig. 8.

The applying plunger is designated by 34 and the same is fitted so as to be capable of a vertical motion, in the frame work of the machine. This applying plunger is made hollow and is provided with small orifices in its face as shown in Fig. 4. A flexible pipe is connected to an opening-in said plunger and a suction device of the ordinary construction, operated by the cam shaft, is connected thereto so that the plunger can 0perate ina way well understood, in paper feeding mechanism. The plunger is.connected by links 35-35 to pivoted arms 3636 which are held down by springs.

These arms carry rollers,v 37'37 which bear on cams It will be noticed that each of these cams has two drops, 380 and 381, as shown in Fig. 7, the drops 380 being less than the drops 381. By this construction, the plunger will have two down-and-up movements for each cycle of operation or each turn of the cam shaft. The first movement due to drops 380, is less when the plunger .moves down into the holding box to take up the transparencies, than when the plunger moves down in drops 381 to apply the transparencies to the envelop blank.

Mounted in the frame-work of the machine, under the' applying plunger 34, is an anvil V for said plunger. The operation can be followed by referring to the last sheet of the drawings. In Fig. 16, the envelop blank A' is shown and in Fig. 17 a transparency T is shown.

I Suppose a machine to be in operation and the holding box to have been filled with transparencies, the operation. .is substantially as follows: Tho holding box moves forward in position under the applying plunger, as shown by the change in position between Figs. 10 and 11. The plunger descends into the holding box, as shown in Fig. 12 and the suctiondevice operates at this time and, as the plunger lifts, the top transparency in' the holding box will be lifted up bythe plunger, as is shown in Fig. 13. The holding box then moves back from position under the plunger, as shown in Fig. 14. The plunger then descends to the anvil V, as shown in Fig. 15-and forcibly applies the transparency in proper position to the gummed envelop blank. This operation is timed to take place lLStllG envelop blank dwells over the anvil. By this operation a single transparency will be accurately applied to the gummed en- I velop blank. The suction device new releases and as the plunger lifts again back'to the position shown in Fig. 10, the transparency will be left forcibly and properly applied to the gummed envelop blank which is then fed forward to the folding box of the machine. By this arrangement, the transparencies can be properly applied in the manufacture of. the envelope, practically at a speed at which the machine can be run. I

I have shown the'attachment as applied to a machine of a specific kind but it is obvious that the same can be applied to machines of other kinds and styles.

The details and arrangements I havejshown and de- Secured on scribed may be greatly varied by skilful mechanics Without departing from the scopc expressed in the claims. v

Having thus fully described my invention, what I of my invention as claim and desire to secure by Letters Patent of the United States is:

iThe combination of a plunger, an anvil, a holding box movable between the plunger and anvil, and means for citing the plunger :1 compound movement comprising a short motion into the box, and second a long motion onto the anvil.

2. The combination of a plunger, an anvil, a holding box movable between the plunger and anvil, means for giving the plunger a 'compound movement, comprising a short motion into the box and second, :1 long motion onto the anvil, and means for withdrawing the box from position between the plunger and anvil after the short motion of the plunger.

ii. A mechanism of the character described, comprising on applying plunger, a holding box, means for moving the holding, box under the plunger, and means for imparting a double to-an'd-fro motion to the plungcryiirst into the holding box and second to apply transparencies, thesecrhenl1 to the plunger, first into the holding box and second on to the anvil. I

The combination in an envelop machine, of. means for applying transparencies, comprising a plunger, a hold lug box, means for moving the holding box under-the plunger, once in each cye'le of operation, and means for giving the plunger a double reciprocating movement in each cycle, the two parts of said movement being of different lengths first into the holding box and second to apply the transparency. v a

6. The combination of an envelop machine having means for applying transparencies, comprising a reciproeating holding box, a plunger, means for reciprocating the holding box under the plunger. once in each cycle of operation, and coils for reciprocating said plunger having two drops for oving the plunger into said holding box and then to apply the transparency.-
